TILE-MOLD.

1 Specification of Letters Patent.

Patented Aug. 15, 1911.

Application filed August 24, 1910. Serial No. 578,765.

To all whom it may concern:

Be it known that 1, JOHN C. MILLER, citizen of the United States, residing at J ackson, county of Jackson, State of Michigan, have invented a certain new and useful Improvement in Tile-Wolds, and declare the following to be a full, clear, and xact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in the general construction of tile molds, and its object is to produce a device which may be easily operated by one person and by the use of which tiles may be quickly made and readily removed from the mold.

Other advantages and improvements will hereafter appear.

In the drawings accompanying this specification:Figure l is a perspective View of the mold. Fig. 2 is a cross-sectional view through the body portion. Fig. 3 is a perspective View of one portion of the wall or shell of the mold. Fig. 4: is a perspective view of the stripping ring. Fig. 5 is a central vertical cross-sectional view of the mold, with parts broken away and in elevation. Fig. 6 is a detail view showing the manner of hinging the hopper to one of the standards. Fig. 7 is a side elevation of the spreading member employed in connection with the collapsible core. Fig. 8 is a perspective view of a slicker employed to smooth and form the upper edge of the tile.

Referring now to the letters of reference placed upon the drawings :A is a base plate provided with radial arms A formed with upstanding ledges a, a, between which rest'the adjustable standards B and B secured to the base plate by bolts 6, b.

C is the outer shell or wall of the mold,

preferably formed of sheet metal in two legs (Z to support it in spaced relation to the base.

E, E, are pedals pivoted at e to the flanges formed in the base plate, their inwardly projecting ends extending beneath the stripping ring whereby the latter may be raised when the pedals are actuated. Additional apertures areprovided in the pedals and flanges of the base plate for purposes of adjustment.

F is a collapsible core, the opposing walls oFf vgjh ich are connected together by springs F is a U-shaped tapering member having a supporting foot portion f, f, perforated for the passage of bolts to secure it to the base plate. As shown in Fig. 5 of the drawings, the tapering member F is located between the opposing walls of the core to spread them apart. Upon raising the core the action of the springs serves to collapse the walls of the core, thereby freeing it from the tile.

G is a hopper pivoted at g to the standard B having lugs 9 adapted to embrace the standard B when the hopper is in position to receive the charge.

B is a handle carried by the standard B for convenience in handling the mold. If desired each of the standards may be provided with a handle.

Having indicated the several parts by reference letters, the construction and operation of the device will be readily understood.

The parts having been assembled as indicated in Fig. l of the drawings, the cement is delivered into the mold through the hopper G and properly tamped, the upper edge of the tile is then finished with a suitable -slickersuch as is shown in Fig. 8 of the drawingsadapted to give the proper formation to its edge. The hopper is then swung on its pivot, as indicated in dotted lines in Fig. 6, and the tile removed in the following mannerf The outer end of the pedals being depressed by the foot of the operator forces the stripping ring upward carrying "with it the tile,the walls of the core moving upwardly with the tile a relatively short distance or until relieved of the spreading action of the tapering member F ,whereupon the springs F, F, cause the opposing walls of the core to collapse freeing them from the tile. The stripping ring with the tile inclosed by the outer shell of the mold is then removed and set in a level position to dry,the shell of the mold being returned at once to the machine and a new stripping ring inserted. Upon swinging the hopper back into position and adjusting the walls of the core to their initial position, the mold is again ready to form a new tile. In order to form the wall of the tile with a tapering end, a ring capable of giving the proper formation is placed on top of the stripping ring before the cement is delivered to the mold, while on the opposite end a slicker is employed adapted to give it the proper shape, as before explained.

Having thus described my invention, what I claim is 1. A mold comprising a base provided with oppositely disposed arms having upstanding edges, grooved standards adjustably mounted on said arms between said edges, semi-circular outer shell sections having flanged abutting edges arranged in the groove of said standard, a ring provided with legs arranged on said base for supporting said shell, pedals mounted on said base engaging said ring, a U'shaped spreading member having tapering side bars fixed on said base, and a sectional core having its sections connected together by springs arranged over said spreading member.

2. A mold comprising a base. provided,

with oppositely disposed arms, grooved standards mounted on said arms, semi-circular outer shell sections having flanged abutting edges arranged in the groove of said standard, a ring provided with legs arranged on said base for supporting said shell, pedals mounted on said base engagingsaid ring, a U-shaped spreading member having tapering side bars fixed on said base, and a sectional core having its sections connected together by springs.

3. In a device of the class described, a base, a pair of standards having grooved edges supported on said base, an inclosing shell formed in sections, the sections provided with outstanding flanges adapted to abut and be supported in the groovesof the standards, a hopper hingedto one of said standards, and lugs formed integral with said hopper designed to embrace the opposite standard to secure the hopper against lateral displacement when in position to receive the charge.

4. In a device of the class described, a base, apair of standards having grooved edges supported on said base, an inclosing shell formed ,in sections,'the sections provided with outstanding flanges adapted to abut and be supported in the grooves of the standards, a hopper hinged'to one of said standards, lugs formed integral with said hopper designed to embrace the. opposite standard to secure the hopper against lateral displacement when in position to receive the charge, and for pivotally connecting the hopper to the other standard.

In testimony whereof, I sign this specification in the presence of two witnesses.
